Genetic Magic Trap: Drugs Designed to 'Fix Genes' Fail to Help Patients
Novartis' experimental drug del-serine failed to meet primary endpoints in a Phase 3 trial for myotonic dystrophy type 1, showing no significant improvement in muscle function. The antisense oligonucleotide approach did not yield clinical benefits, highlighting challenges in rare disease drug development. This setback follows another failure in Novartis's neuromuscular portfolio, raising questions about its strategy in this area.
